Deadly Bird Flu: first US death shocks Louisiana

A heartbreaking milestone has struck the United States. Louisiana health officials confirmed the country’s first death from H5N1 bird flu. The victim, over 65 years old with underlying health issues, had been hospitalized after contact with a backyard bird flock and wild birds.

Experts sound the alarm

Flu specialists have long warned about the dangers of the H5N1 virus. Dr. Richard Webby, a top influenza expert at St. Jude’s Children’s Research Hospital, called this virus the “nastiest form” they’ve seen in 25 years of research. “This fatal case is tragic, but not surprising,” he said.

Global history of Bird Flu

Since 2003, around 900 human bird flu infections have been reported worldwide. About half of those infected died, according to the World Health Organization (WHO). This points to a shocking 50% fatality rate. However, experts believe mild cases often go unreported. Realistically, the fatality rate may be closer to 5%, still making it a deadly virus.

In comparison, the original strain of COVID-19 had a case fatality rate of 2.6%.

What happened in Louisiana?

The Louisiana patient contracted the D1.1 strain of H5N1, which has been spreading in wild birds and poultry. This strain differs from one circulating among dairy cattle. Scientists are uncertain if D1.1 causes more severe illness in humans.

The virus’s genetic analysis revealed mutations that enhance its ability to infect human upper airways. These changes weren’t found in the birds the patient interacted with. Experts suspect the mutations evolved within the patient’s body, raising concerns about human-to-human transmission.

Canadian and U.S. cases linked

D1.1 has infected others outside Louisiana. A critically ill 13-year-old girl in Canada was hospitalized but survived. Her exposure source remains unknown. In Washington, poultry farm workers also tested positive for milder cases of D1.1.

Ongoing investigations

The CDC continues to analyze the Louisiana case. They’re studying serial blood samples to understand how the virus evolved in the patient. Dr. Seema Lakdawala, an influenza expert at Emory University, stressed the importance of preventing future infections to avoid viral mutations and outbreaks.

The CDC stated Monday that the overall threat level from H5N1 remains low. “No person-to-person transmission has been identified, and no concerning mutations are spreading among wild birds or poultry,” the agency noted.

How to stay safe

Health officials urge caution, especially for people exposed to birds. Backyard bird owners, poultry farmers, and those in contact with sick or dead animals must remain vigilant.

Watch for symptoms:

• Breathing problems
• Red eyes

If symptoms appear within 10 days of exposure, inform a healthcare provider immediately.

Safety tips:

1. Avoid touching sick or dead animals and their droppings.
2. Keep pets away from wildlife.
3. Cook poultry and eggs thoroughly to eliminate risks.
4. Avoid raw milk or unpasteurized dairy products.
5. Report sick or dead animals to the USDA hotline: 1-866-536-7593.
6. Farmworkers should consider flu vaccinations to prevent dual infections.

The big picture

America’s first bird flu death is a wake-up call. The H5N1 virus is evolving, and experts urge everyone to minimize risks. While the general public’s threat remains low, staying informed and cautious is essential. By taking simple precautions, we can help prevent future tragedies.
